[Specific implementation method]

[0021] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0022] The present utility model only protects the mechanical structure, and the circuit structure is common knowledge.

[0023] A sensor for pulling motion, such as Figure 1 to Figure 5 As shown, it includes a shell 1, an upper cover 2 and a bottom cover 3 and is fixedly connected by screws. A deformable member 4 is provided in the shell 1, and a resistance strain gauge 5 is provided at the center of one side of the deformable member 4. A first connecting member 6 and a second connecting member 7 for installing a tension rope or a tension spring are fixedly installed at both ends of the deformable member 4 and on both sides of the deformable member 4, respectively. One end of the first connecting member 6 and the second connecting member 7 connected to the tension rope or the tension spring extends outward from the shell 1 and the extension direction is located on the center line of the deformable member 4, so that the tension only acts on the deformable member 4, and the tension received at both ends of the sensor cancels each other for the shell 1, and no interaction force is generated between the shell 1 and the deformable member 4, so as to ensure that the shell 1 will not be damaged by the tension. A circuit board 8 electrically connected to the resistance strain gauge 5 is provided in the housing 1, a battery 9 is provided in the housing 1 and below the circuit board 8, a display screen 10 is provided on the circuit board 8, and a display window 11 is provided on the upper cover 2 corresponding to the display screen 10. The deformable member 4 and the resistance strain gauge 5 produce a slight deformation according to the tension exerted on the first connecting member 6 and the second connecting member 7, and can feed back an electrical signal to the circuit board 8. The number of tensions is recorded, the magnitude of tension is calculated and displayed through the single-chip microcomputer on the circuit board 8, and the target duration or number of tension exercises can be set at the same time, and the corresponding data is displayed through the display screen 10, thereby enhancing the interest of the tension exercise and enabling users to use the tension rope or tension spring for exercise more reasonably.

[0024] Specifically, the first connecting member 6 and the second connecting member 7 are L-shaped and both include a fixed end 12 and a connecting end 16. The deformable member 4 is a rectangular parallelepiped. The first connecting member 6 and the second connecting member 7 are symmetrical with respect to the diagonal of the deformable member 4 to ensure the force balance at both ends of the deformable member 4, avoid the generation of interaction force between the deformable member 4 and the shell 1, cause the deformable member 4 to move, and affect the sensing accuracy of the resistance strain gauge 5.

[0025] In addition, screw holes 14 are provided at both ends of the deformable member 4, and through holes 13 are correspondingly provided at the fixed ends 12 of the first connecting member 6 and the second connecting member 7. A fixing screw 15 that is screwed into the screw hole 14 is provided in the through hole 13. When the fixing screw 15 is screwed in to fix the connection, a gasket can be nested to adjust the gap between the first connecting member 6 and the second connecting member 7 and the deformable member 4 to avoid affecting the sensing accuracy of the resistance strain gauge 5. At the same time, the gaps in the through hole 13 and the screw hole 14 are filled with glue to reduce wear caused by long-term use and prevent loose connection. A connecting hole 17 is provided at the connecting end 16 of the first connecting member 6 and the second connecting member 7. When using the sensor, it is only necessary to buckle one end of the tension rope or tension spring into the connecting hole 17 on the first connecting member 6 and the second connecting member 7 with a movable lock.

[0026] Specifically, the material hardness of the first connecting member 6 and the second connecting member 7 is higher than that of the deformable member 4, so as to prevent the first connecting member 6 and the second connecting member 7 from deforming before the deformable member 4 when subjected to tension, thereby affecting the sensing accuracy.

[0027] Specifically, a first positioning socket 18 and a second positioning socket 19 are respectively provided on both sides of the shell 1, and the connecting ends 16 of the first connecting member 6 and the second connecting member 7 can be movably inserted into the first positioning socket 18 and the second positioning socket 19 respectively to avoid displacement of the connecting ends 16 of the first connecting member 6 and the second connecting member 7.

[0028] In addition, a support plate 20 is provided on the inner wall of the shell 1 and at both ends of the deformable member 4, and a limiting slot 21 is provided on the support plate 20. One end of the deformable member 4 can be movably clamped in the limiting slot 21. The limiting slot 21 can prevent the deformable member 4 from being greatly offset and affecting the force balance on both sides.

[0029] Specifically, a buzzer 22 and a charging interface 23 are also provided on the circuit board 8 . The buzzer 22 can remind the user after the user reaches the set number or duration of pulling exercise. A button 24 is provided on the upper cover 2 and on one side of the display screen 10 .

[0030] In addition, a dust plug 26 is detachably provided on the housing 1 corresponding to the charging interface 23 , and a protective sheet 25 is provided in the display window 11 .

Various modifications and changes may be made without departing from the scope thereof. Various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field without departing from the design concept of the present invention shall all fall within the protection scope of the present invention.
